GENERAL DESCRIPTION
The ML60852A is a general purpose Universal Serial Bus (USB) device controller.
The ML60852A provides a USB serial interface engine, USB transceiver, FIFOs, control/status registers,
application interface circuit, and oscillation circuit thereby easily realizing a USB system. The ML60852A
supports four types of data transfer such as control transfer, bulk transfer, interrupt transfer and isochronous
transfer, and also supports five or six endpoints.
FEATURES
• USB1.1 compliant
• Supports full-speed (12 Mbps).
• Supports four types of transfer; control transfer, bulk transfer, interrupt transfer, and isochronous transfer.
• Endpoints: 5 to 6 endpoints
Control EP
1
Bulk/interrupt EP
3
Isochronous/bulk/interrupt EP 1 or 2
• Built-in FIFO for data storage
• A two-layer configuration of FIFO for each of EP1, EP2, EP4, and EP5
• 8/16 bit DMA supported (EP1, EP2, EP4, and EP5)
• Intelligent Serial Interface Engine (SIE)
• Supports bus-powered device.
The suspend condition is automatically detected and the low-power mode is activated. Normal operation is
automatically restarted when the resume condition is detected.
